  • Patent number: 4538372
    Abstract: A releasable downrigger clip is disclosed having a finite length of spring wire and having a first segment thereof at a first end doubled back upon itself to define an eyelet and a releasable clasp enabling an intermediate segment of an elongate downrigger wire to be received in the eyelet by passing between the spring wire and the releasable clasp. A second segment of wire at the opposite end of the finite length is also doubled back on itself to define a hook. A closed loop is provided in the segment of the wire intermediate the opposite ends with the opposite ends of the loop resiliently engaging each other but being separable against the resilient urging caused by the resilience of the spring wire. In use, the clip is adapted to releasably engage the downrigger wire which extends from the downrigger arrangement to a weight connected at a free end thereof beneath the surface of the water.
